  • Patent number: 11381012
    Abstract: An electrical connector includes a conductive housing having a first receiving portion with an open end, a movable terminal having a first end inserted into the first receiving portion via the open end, the movable terminal having a second receiving portion, and a first elastic piece located in a space defined by the first receiving portion and the second receiving portion. A second end of the movable terminal opposite to the first end protrudes movably out of the first receiving portion against an elasticity of the first elastic piece. The first end of the movable terminal has a first elastic arm elastically abutting an inner side wall of the first receiving portion. The movable terminal is electrically connected to the conductive housing by each of the first elastic piece and the first elastic arm.

  • Patent number: 11264753
    Abstract: A connector includes a pair of outer conductors including a first outer conductor and a second outer conductor assembled together and slidable with respect to each other, a pair of center conductors arranged within the outer conductors, an insulation seat, and an elastic element. The center conductors include a first center conductor and a second center conductor assembled together and slidable with respect to each other. The first outer conductor and the first center conductor are fixed to the insulation seat. A first end of the elastic element abuts against the first outer conductor or the insulation seat. The first outer conductor and the first center conductor are both in electrical contact with a first electrical component under a pressing force from the elastic element.
